Method for locating and circumscribing text areas on a master which may contain text, graphics and/or image areas










Image Number 9 for United States Patent #4513442.

A method for locating and circumscribing text areas on a master which may contain text, graphics and/or image areas employs the steps of optoelectronically scanning the master, digitizing the analog signals obtained from the scanning, processing the digital values for forming a plurality of isolated black blocks, and statistically analyzing the coordinates corresponding to the beginning and the end of the black blocks in order to obtain a statistical decision as to whether a particular black block being analyzed represents a line of text.
